In order to prepare for the role, Lily had to lose weight – something that she was understandably worried about, given her own personal history. The actress told Refinery29 that it was a "scary process," but she added: "I knew that, this time, I would be held accountable for it. I would be [losing weight] under the supervision of a nutritionist and surrounded by all these amazing women on set. So, I knew that I would be in a safe environment to explore this."

Along with her weight loss, however, came comments from other people – some of which were pretty problematic. In a recent interview with The Edit, Lily revealed that she even received a compliment about her drastic decline in weight. "I was leaving my apartment one day and someone I've known for a long time, my mom's age, said to me, 'Oh, wow, look at you!'" the actress recalled. "I tried to explain [I had lost weight for a role] and she goes, 'No! I want to know what you're doing, you look great!' I got into the car with my mom and said, 'That is why the problem exists.'"

Part of the issue here, of course, is that society has wired us to view weight loss as something to compliment people on. Thanks to unrealistic beauty standards, so many people view thinness as an "accomplishment," like the person Lily encountered. These types of comments can be harmful to anyone, but especially to someone who has experienced an eating disorder in the past. Praise over weight loss can easily be triggering to someone who has engaged in eating disorder behaviors, which is why the National Eating Disorders Association encourages friends and loved ones to avoid commenting on weight or physical appearance at all. Instead, they advise to "focus on positive personality traits and other qualities that have nothing to do with appearance." It's a good rule of thumb for anyone; after all, you never know what someone might be struggling with internally.
